A HOST PLANT LIST OF APHIDS IN THE VICINITY OF 
THE UNIVERSITY OF FLORIDA 1 

By Arthur C. Mason 

Our present literature on the insect life of Florida contains 
very few references to aphids. In fact, only a few species which 
are of economic importance are even mentioned, and nothing 
like a list of those occurring in the State has been attempted. 
While this paper does not contain a complete list of the plant 
lice of Florida or even this section of the State, still it may serve 
as a start toward such a list, and may be added to from time 
to time. 

Previous references include Aphis brassica on cabbage (31) 
(32), Myzus persicae on peach and tomatoes (26) (36), Me- 
goura solani on tomatoes (35) (36), Aphis gossypii on cotton, 
cucurbits, and orange (2) (22) (31) (32) , Siphonophora cucur- 
bitae on egg-plant (32), Aphis maidis on corn (1), and Tox- 
optera graminum on oats (37). These are dealt with purely 
from an economic standpoint. 

Lists of aphids have been written by several entomologists 
for various sections of the country, but none of them cover 
Florida. While it is true that a large number of plant lice are 
widely distributed and found in practically all the states, some 
others may be restricted to this part of the country alone. There- 
fore, a complete list for this State should be prepared. 

The insects listed were collected over a period of two years 

1 Taken from thesis entitled "Systematic and Biological Studies of Some Florida 
Aphididae," presented by the writer to the University of Florida in 1915 for the 
degree of Master of Science. 

This paper constitutes Part I exclusive of sections on methods of collecting, 
mounting, etc. Parts II and III together with references cited will appear in later 
issues.

(1913-1915) and during all seasons. They represent those found 
on both cultivated crops and wild plants. The former, of course, 
are brought to the attention of economic workers much more 
often because of their importance to agriculture and also their 
greater abundance. The list represents about 30 species of 
aphids. Many others collected could not be determined because 
of lack of mature specimens or winged forms. Undoubtedly 
there are in the state many undescribed species of plant lice 
and at least two of these were found. 

Permanent mounts were made of all specimens and are in the 
author's collection. Natural colors cannot be retained in mount- 
ed slides and color notes must be made from the live specimens.
